Our Team

At DCA, our different backgrounds and experience are one of our greatest strengths. They allow us to look at drilling challenges from different perspectives while staying focused on what we know best: improving drilling performance.

We approach every operation with humility. We do not assume we know an operation better than the people running it every day. Instead, we combine their knowledge with an independent outside perspective, proven methods and deep drilling expertise.

Sometimes that outside view helps identify issues and opportunities that are difficult to see from within a complex mining operation. Read our company ethos
